Watch out, Georgetown Cupcake: There are some new dessert-slinging sisters on the block—literally. The Pie Sisters of Georgetown—a shop formerly known as O’ B. Sweet—is setting up shop on M Street, Northwest, in November, just one year after it got is start in the owners’ mother’s kitchen in Northern Virginia. Their booming business is proof of something we’ve suspected for awhile: Pie is one of the hot desserts for weddings these days.

And why shouldn’t it be? “Pie is special in the sense that it is part of so many families’ traditions,” says Allison Blakely, who founded Pie Sisters last October with her sisters, Erin and Catherine. “Pie flavors also bring the best of the season to the rest of the celebration.” With favorites such as Classic Apple, Bourbon Chocolate Pecan, and Pumpkin Spice on the menu for autumn, we’re sure to start seeing the Pie Sisters treats pop up on fall-inspired dessert buffets around the area.

But what about the buttercream colors and initialed adornments that make a cupcake or layer cake so customizable? “Every bride wants something special and different,” says Blakely. “We can tailor the decorations specific to each bride’s taste.” The Pie Sisters shop offers custom pastry cut outs (hearts, initials, seasonal decorations) and can add in colors to complement the bride’s theme. For guest favors, it will individually package “cuppies” (mini cup pies) and can personalize the box for the bride.

The Pie Sisters menu changes seasonally, but each flavor offered is available in three sizes: a three-inch cuppie, a seven-inch round, and the classic nine-inch, which comes in a glass pie dish. Five of the season’s most popular flavors are available gluten-free. A cookie menu is also in the works, with classics such as Chunky Chocolate Chip, Oatmeal Raisin, and White Chocolate Macadamia on offer now.

You’ll have to wait until November to visit the first Pie Sisters of Georgetown storefront, but you can find menus and place an order at piesisters.com.
